Hello - I have a 1986 European 5 speed 300 Diesel (124 body) that has what I call "dart arama" when cruising. I had read somewhere in this forum about some issue associated with rear control arms or the like causing this problem. I am not that experienced with the suspension on my "work horse diesel" but given its age, I want to dive in and start a gattlin gun approach to replacing the shocks, upper & lower control joints, steering dampner etc but on a priority basis - first being to correct this swaying at higher speeds. The sway is similar to cruising along at 65 and getting a gust of side wind...Can anyone point me in the right direction??......thanks!
